non-linear functions
Average Rate of Change is used primarily with non-linear functions, since all linear functions have a constant rate of change.
Which graph has a y-intercept of -1/2?
Answer:
C.
Step-by-step explanation:
Y-intercept basically means where on the graph does the line "cut" through the y-axis (the vertical line). In the graphs, there is only one line which cuts through the y-axis at -1/2, which is C. .
Ella buys 5 packs of muffins. She uses a coupon and saves $3 off the total. Which expression represents her total cost?
A. 5m -3
B. 5 -3m
C.5+3
D. 5m + 3
Answer:
The answer is A. 5m - 3
Step-by-step explanation:
Ella bought 5 packs of muffins but since we don't know how many muffins are in each pack, we put a variable in place so it's 5m. Since she saved $3 off the total, that means you would subtract 3 from the total, so the problem would be 5m - 3
A breakfast menu liste 3 eggs with 2 sausage for $4.15 or 4 eggs with 1 sausage for $4.30 . What is the cost of 1 egg, and what is the cost for 1 sausage?
Answer:
Cost of 1 egg = x = $0.89
Cost of 1 sausage = y = $0.74
Step-by-step explanation:
Let the:
Cost of 1 egg = x
Cost of 1 sausage = y
A breakfast menu lists:
3 eggs with 2 sausage for $4.15
3x + 2y = 4.15......Equation 1
4 eggs with 1 sausage for $4.30 .
4x + y = 4.30...... Equation 2
y = 4.30 - 4x
We substitute 4.30 - 4x for y in Equation 1
3x + 2(4.30 - 4x) = 4.15
3x + 8.6 - 8x = 4.15
3x - 8x = 4.15 - 8.6
-5x = -4.45
x = -4.45/-5
x = $0.89
Solving for y
y = 4.30 - 4x
y = 4.30 - 4(0.89)
y = 4.30 - 3.56
y = $0.74
Therefore,
Cost of 1 egg = x = $0.89
Cost of 1 sausage = y = $0.74

what is the maximum value of f(x)=−4x2+4x−2?
Answer: -1
Step-by-step explanation: A typical quadratic equation is [tex]ax^{2} +bx+c[/tex] and the maximum value formula is -b/2a, so let plug it in -4/2(-4) which equals 1/2. Then let plug 1/2 into the equation,
-4(1/2)^2+4(1/2)-2=
-1+2-2=

Answer:
[tex]\approx 26.16\:\mathrm{m}[/tex]
Step-by-step explanation:
Let [tex]h[/tex] be the height of the tree. In reference to the tree and bird, a right triangle is formed. We can write the following trig function for that right triangle:
[tex]\tan28^{\circ}=\frac{h}{15},\\h=15\tan28^{\circ},\\h\approx 7.98\:\mathrm{m}[/tex].
Now we can use this to find the hypotenuse of this triangle (the distance between the cat and the bird):
Let the distance between the cat and bird be [tex]k[/tex]. Then,
[tex]7.98^2+15^2=k^2,\\k\approx 16.99\:\mathrm{m}[/tex]. This is one side of the triangle that is formed by the cat, bird, and mouse.
The right triangle formed by the tree, cat, and mouse shares the height [tex]h[/tex] with the other right triangle, as we found earlier. Let [tex]l[/tex] represent the hypotenuse of this triangle or the distance between the cat and mouse. We then have the following trig function:
[tex]\sin 40^{\circ}=\frac{7.98}{l},\\l=\frac{7.98}{\sin40^{\circ}}\approx 12.41\:\mathrm{m}[/tex]. This is another side of the triangle that is formed by the cat, bird, and mouse.
The triangle that is formed by the cat, bird, and mouse has shares an angle of [tex]125^{\circ}[/tex] with the base of the auxiliary pyramid. The other angles, however, are not shared.
Since we have two sides and the angle between these two sides, we can use the Law of Cosines to find the other side (the distance between the mouse and bird). The Law of Cosines is given by:
[tex]m^2=k^2+l^2-2kl\cos M[/tex], where [tex]m[/tex] is the distance between the bird and the mouse and the other variables are defined above.
Plugging in values, we get:
[tex]m^2=16.99^2+12.41^2-2\cdot16.99\cdot12.41\cdot\cos 125^{\circ}[/tex]
Solving, we get:
[tex]m\approx \fbox{$26.16\:\mathrm{m}$}[/tex].

Answer:
angle v equals 75.8 degrees
Step-by-step explanation:
since the lines parallel, then angle u and angle v would be the same as they are alternate interior angles. you can also subtract 180 with angle w to find angle v as well (180 - 104.2 = 75.8)
Paulo sells 249 medium pumpkins for $8 each and 84 large pumpkins for $14 each. How much money does Paulo collect selling the medium and the large pumpkins
Answer: $3,168
Step-by-step explanation:
Paulo sells 249 medium pumpkins for $8 each. The money Paulo makes from this is:
= 249 * 8
= $1,992
Paulo also sells 84 large pumpkins for $14. The money made is:
= $1,176
Total from selling both is:
= 1,992 + 1,176
= $3,168

Maria makes a fruit salad.
The table shows the amounts of different kinds of fruit that she uses.
Kind of Fruit Amount
Grapes 323 cups
Melon 214 cups
Pineapple 234 cups
Strawberries ?
The amount of strawberries that Maria uses is 38 times the amount of the other fruits combined.
How many cups of strawberries does Maria use?
Answer:
If my calculations are correct it would be 6,168 cups of strawberries
Step-by-step explanation:
If it’s 8 times the amount of them combined then you add all of the other fruit together and then multiply by 8 giving you:
323+214+234=771
771*8=6,168 cups of strawberries.
Only in math would someone need that much fruit
Find x and y so the quadrilateral is a parallelogram.
Answer:
We conclude that:
The value of x = 7The value of y = 4Step-by-step explanation:
Given
The parallelogram PQRSWe know that the diagonals of a parallelogram bisect each other.
so
[tex]RT = TP[/tex]
Given
RT = xTP = 5x-28so substituting RT = x, and TP = 5x-28
[tex]RT = TP[/tex]
[tex]x = 5x-28[/tex]
[tex]5x = x+28[/tex]
[tex]5x-x = 28[/tex]
[tex]4x = 28[/tex]
divide both sides by 4
[tex]4x/4 = 28/4[/tex]
[tex]x = 7[/tex]
Therefore, the value of x:
x = 7Similarly,
[tex]QT = TS[/tex]
Given
QT = 5yTS = 2y+12so substituting QT = 5y, and TS = 2y+12
[tex]QT = TS[/tex]
[tex]5y = 2y+12[/tex]
[tex]5y-2y = 12[/tex]
[tex]3y = 12[/tex]
divide both sides by 3
[tex]3y/3 = 12/3[/tex]
[tex]y = 4[/tex]
Therefore, the value of y:
y = 4
Therefore, we conclude that:
The value of x = 7The value of y = 4Plzzzzzz help

y = a + x
y = 1 X
y = 4 + x
y = 4x
Answer:
The equation of the graph is;
y = 4·x
Step-by-step explanation:
The coordinates of two points, (x₁, y₁), and (x₂, y₂) respectively on the straight line graph are;
(-3, 12), and (2, 8)
The slope, m, of the straight line graph is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, by substitution of the values, we have;
[tex]Slope, \, m =\dfrac{8-(-12)}{2-(-3)} = \dfrac{8 + 12}{2 + 3} =\dfrac{20}{5} = 4[/tex]
The equation of the graph in point slope form is therefore;
(y - 8) = 4×(x - 2)
y = 4·x - 8 + 8 = 4·x
y = 4·x.
